Garage construction and repair in MetroWest and Worcester County
Cars that stay out of the snow, a workbench with its own lights, storage that does not spill into the house. We build attached and detached garages that look like they were always part of the property, and we repair garages that have been damaged.

Garage construction at Gamache Construction
Gamache Construction is a family-owned general contractor based in Northborough, Massachusetts that builds and repairs attached and detached garages for homes across MetroWest and Worcester County. In business since 2006, the company is run by owner Chris Gamache, who leads three construction crews and brings in electricians as each garage needs them. Garages are planned around the lot, the number of bays and how you will use the space, with the roofline, siding, doors and trim matched to the house. The company handles the building permit and inspections, helps with the insurance side of structural repairs, and provides a free, detailed written estimate before work is scheduled. Labor is covered by a warranty.
What kind of garage can we build?
Start with how many cars and how much else needs to fit, then decide what the space should do besides parking.
Attached garages
Shares a wall with the house, so you walk inside without going out in the weather.
Detached garages
A standalone building placed where the lot and the driveway work best.
Single and multi-car
One bay for a single car up to multi-bay layouts for vehicles, a boat or equipment.
Storage
Wall space, shelving areas and clear floor planned for bikes, tools and seasonal gear.
Workshop space
Room for a bench and tools, with the outlets and lighting a workshop needs.
Temperature control
Insulation and climate options for a garage you plan to work in year-round.
Loft storage
Storage overhead in the roof space, reached by stairs or a ladder.
Custom exterior finishes
Carriage-style doors, siding, trim and roofing chosen to suit the house.
Can a damaged garage be repaired?
Yes. We repair garages with structural damage, such as a corner hit by a car, and we help with the insurance side of the claim.
A repair starts with a look at what is actually damaged behind the siding. The written estimate spells out the structural work, so you and your adjuster are looking at the same scope. When the repair is done, we finish and paint enough of the wall that the fixed section blends in.
“Gamache Construction did a great job repairing my garage after a corner was hit by a car and needed structural repair. Very clear estimate provided and work was completed in a timely manner. They even painted the whole side of the garage to ensure continuity. Well done!”

Attached or detached: which fits your property?
The lot, access from the street, local zoning and how you plan to use the space decide it. Here is how the two compare.
Attached garage
- Direct entry into the house from the garage
- Its roofline has to meet the existing roof cleanly
- Uses the side of the house, so it depends on room between the house and the lot line
- Shared wall needs the right fire separation and a proper door into the house
Detached garage
- Can sit wherever the driveway and yard work best
- Keeps workshop noise and fumes away from the living space
- Stands as its own building, styled to match the house
- Needs its own electrical feed if you want power and lights
How Gamache Construction plans a garage that looks original to the property
New garages and garage repairs run through the same four steps, and the rooflines, siding, doors, windows and trim are matched to the house before anyone breaks ground.
Look at the lot
We look at the lot, the driveway and the house, or at the damage if it is a repair, and note the roof pitch, siding and trim the garage should echo.
Pick the details in writing
Roof pitch and overhangs, siding profile, corner boards, and doors and windows in a style that fits (such as carriage doors on an older home) go into a written estimate with the options and the price before work is scheduled.
Permit, foundation, frame
We file the permit. Chris Gamache runs the crews on the foundation, framing, roof, siding and doors, electricians come in for the wiring, and inspections happen along the way.
Final walkthrough
We walk the finished garage with you before the job is closed out.
What determines the cost of a new garage?
The written estimate after the site visit prices your garage on your lot. A garage budget starts with its footprint and foundation, then follows the doors and finishes you pick.
Financing a garage
Financing is available for garage projects. The financing page covers how to apply.
Financing- Number of bays and footprintEach added bay adds foundation, framing, roofing and a garage door.
- Foundation and site prepSlab and frost walls, grading, and any driveway extension to reach the doors.
- Attached versus detachedTying into the house adds roof and wall work; a detached garage needs its own power run.
- Doors, windows and finishesCarriage-style doors, metal roofing and matching siding cost more than basic options.
- Extras insideLofts, workshop wiring, insulation and climate control are priced as their own lines.
Do you build both attached and detached garages?
Yes. Which one fits depends on your lot, driveway access, local zoning and how you plan to use the space, and we work through that at the site visit.
Can the garage include a workshop or a storage loft?
Yes. Workshops, loft storage and temperature-controlled space can be designed in, with the wiring and lighting they need.
Will a new garage match my house?
Yes. We coordinate the rooflines, siding, doors, windows and trim with the house so the garage reads as part of the property.
Who handles the permit for a garage?
We do. We file the building permit and coordinate the approvals and inspections with your town.
Can you help with insurance after a car hits the garage?
Yes. We assess the structural damage, provide a clear written estimate and help with the insurance side of the repair.
Do you paint the garage after a repair?
Yes. We paint enough of the surrounding wall, up to the whole side, so the repaired section matches the rest of the garage.
Who replaces the roof on my existing garage or house?
Reroofing an existing house or garage goes to our roofing division, Roofing by Gamache. The roof on a new garage we build is part of the construction job.
